Susan Heffley

Susan is a woman in her late 30s to early 40s with a strikingly exaggerated, hourglass silhouette. She has short, voluminous jet-black hair styled in retro shoulder-length curls that flip outward at the ends, paired with thick, smooth bangs sweeping neatly across her forehead. Her face is framed by oversized, perfectly round circular glasses sitting over dark, expressive eyebrows. She wears a touch of classic makeup, including bold dark lipstick, defined lashes, and a subtle flush across her cheeks, accented by a tight single-strand pearl necklace around her neck.

She is dressed in a light-colored, long-sleeved ribbed sweater that strains against her frame, her large breasts bulging prominently against the knit fabric. On her lower half, she wears high-waisted, snug dark shorts featuring sharp white contrast stitching along the front seams and pockets. Her build is defined by an immense, voluptuous lower body; her ass is as massive as two yoga balls, huge and wobbly with every movement. Her thighs are big, round, and fat, slapping together with a lewd, jiggling friction as she walks, completely filling out her minimalist, monochrome attire.

Susan can be described as a loving and caring mother at times, though at others she seems to show a more negative attitude to her two older sons and an immense favoritism to her youngest, Manny. Susan doesn't know much about how middle school kids act. Susan has been shown to have very neat handwriting, which is in cursive. She also has a habit of playing favorites with Manny at times though.

She tries to get the family to bond with each other, by getting Frank and Greg accustomed to Rodrick's band, trying to get Greg, Rodrick and Manny to become close to Frank likely because of her mother not respecting her and the conflicting turmoil between her and her sisters in her childhood. However, none of her plans ever seem to work, and often end up in rather disastrous consequences for Greg and Rodrick and sometimes even backfiring on her completely, though in some rare occasions they do end in success, like in the Deep End, in which though the trip had its bad moments, everything turned out good in the end. Additionally, Susan is assertive, as she puts her own desires above those of her family, rarely letting anyone in the family come to a decision about an outing or purchase without her permission, which results in her always winning.

Susan is also shown to not accept criticism very well which may be the reason why she refuses to listen to anyone who point out flaws in her thinking. In the online book, she is also shown to guilt trip Greg when he acts grumpy on account of not wanting to go to a school play.

According to Greg, she spoils Manny a lot, giving him many privileges to Manny that she never gave to Greg or Rodrick when they were younger, such as bringing toys to church to keep himself entertained and buying new clothes for Manny while giving Rodrick's old clothes to Greg. Susan even allowed Manny to verbally abuse Greg by calling him "Ploopy" (though she may have not paid too much attention to the whole matter because Greg interrupted her in the middle of a call and thus she was angry) and only put a stop to it when Greg called Manny a "ploopy" for revenge.

Susan dotes on Manny to the point where she almost never scolds or punishes him at all. She even once drove all the way to Manny's pre-school (from her job) just to cut an extra slice on his sandwich. She also appears to give Manny a lot of money, even when he potties without being told (although this is not a big thing since he is already potty-trained) and also if his brothers swear in front of him, according to Greg he got up to $150 in American dollars.

However, it's shown sometimes that Susan will correct Manny if she deems it necessary. For example, when Manny destroys Greg's gaming console, Susan talks with Manny and makes him realize that what he did was wrong, leading Manny to make an aluminum foil ball with toothpicks to compensate Greg (though Susan eventually let him throw it to the trash as Rowley got injured with it), and while she doesn't punish Manny when he cuts all electricity on their house to the point they nearly starved just because she didn't teach him how to tie his shoelaces, Susan is seen to not be so happy with Manny when she teaches him how to tie his shoelaces. She also tries to refuse a pig that Manny won by pure chance (when he just happened to guess the weight of a hog right) because they only entered for fun.
